All Copper Loopbacks are 1-3, 2-6, 4-7, 5-8 pin out unless specified by the client.
All Copper Jumpers are 1-3, 2-6, 3-1, 4-4, 5-5, 6-2, 7-7, 8-8 unless specified by the client.
Custom cabling configurations can be made for any scenario.

Fiber Optic Loopback Test Fixtures include custom configurations for single and multi-port SC Test Fixtures (sometimes referred to as GBIC Test Fixtures), LC Test Fixtures (sometimes referred to as Small Form Factor Test Fixtures), MTRJ Test Fixtures and others, upon request. Attenuated Test Fixtures are available for any of the models listed. Test fixtures may either be, Loopback (optical signal loops back within connector or test fixture device) or port-to-port (where the optical signal loops from one test fixture to another with a cable between them).

Copper Cable Test Fixtures include custom configurations for multi-port RJ45 Loopback Test Fixtures, DB9 Test Fixtures, Telco or Centronics 50 Test Fixtures, SCSI Test Fixtures and others, upon request.

Cypress Industries has also designed Fiber Optic and Copper test fixture devices for our test fixtures. This will allow you to quickly determine if an operator error has been made in the testing process. LEDs will illuminate when ports are working properly. Custom handling and storage fixtures are also available for the test fixtures listed. These will also expedite the testing process by decreasing handling times.

All Cypress Industries products are 100% inspected and electronically tested.
